Sad day, guys: Brittany Murphy (who got her start in Clueless and went on to star in movies like Girl, Interrupted, Just Married, Uptown Girls, and dozens of other films) died last night. According to Gawker, Murphy died after going into cardiac arrest, which could be the result of some underlying condition or drug use.

Our thoughts go out to her family, especially her husband, screenwriter Simon Monjack.
